2026 GASGAS MC 250

Electronics

• ENGINE MANAGEMENT SYSTEM (EMS): Small, light, and fast at processing data, just what you need from an engine management system! The Vitesco Technologies component is the best in the business and includes a rollover sensor that cuts the ignition during big crashes, as well as feeding information to the hour meter. Plus, our 2-strokes feature an improved wiring layout for added durability and reduced risk of electrical issues
• MAP SELECT SWITCH: Installing the Map Select Switch from the GASGAS Technical Accessories range really makes the MC 250 sing! It offers a choice of two maps, and they're both awesome. The mellow (white) map - Map 1 - delivers that classic, smooth 250cc 2-stroke power that everyone loves. Flick it to the aggressive (green) map - Map 2 - and you'll feel a sharper, more explosive throttle response. Ideal for deep sand tracks!
• THROTTLE BODY: The MC 250 uses a 39mm Keihin throttle body with its injectors positioned to ensure the most efficient flow of fuel mixture into the combustion chamber. But what's most important to all riders is the fact that the direct cable mounting design ensures instant throttle response.
• ELECTRIC STARTER: The best invention since the wheel! With an electric starter fitted, this GASGAS starts super easily every single time you hit that start button. And to simplify things further and save space on the bars, the engine stop button is located in the same housing as the start button. Using a Li-Ion battery, which weighs approx. 1kg less than a conventional lead battery, you get the convenience of electric starting while the overall bike weight is kept to a minimum. It's a win, win for everyone!

Handling

• FRAME: The current frame hits the sweet spot between razor-sharp handling and just the right amount of flex. Lightweight motor mounts dial in the feel without messing with straight-line stability, and smart material tweaks, like a slimmed-down upper shock mount and reduced wall thickness up front, save 300g. Developed with the GASGAS Factory Racing crew, it's a setup that stays planted and lets you push harder in every turn with a big smile in your face.
• SUBFRAME: The all-aluminum subframe is light, strong, and works as one with the mainframe by helping to centralize mass and contributing massively to the bike's outstanding handling characteristics.
• TRIPLE CLAMPS: Forged aluminum triple clamps offer just the right amount of calculated flex thanks to a more forgiving steering stem. The triple clamps align the fork tubes perfectly for a smooth action, which improves front wheel feedback and leads to predictable handling on any track and any terrain. The adjustable bar mounts with the slightly larger contact area against the handlebars reduce the chance of the bars twisting. A glass bead blasted finish means the triple clamps always look as good as new.
• WP FORKS: Our GASGAS motocross models come with a 48mm, split air WP XACT fork with model specific set ups to ensure the best performance. Continuing to be easily adjustable by hand on the outside, on the inside, a capsulated air spring and pressurized oil chamber take care of delivering consistent damping. By using an air spring, a customized set-up can be created easily as this bike includes an air pump to adjust the pressure. And, for those who like to go big on the jumps, a hydrostop in the forks help maintain forward momentum by taking the sting out of every heavy landing.
• WP SHOCK: With no less than 300mm of travel, the WP XACT rear shock effortlessly absorbs even the biggest bumps. While the shock remains the same, it continues to deliver top-tier performance, thanks to years of development and feedback from the MXGP circuit. The settings are fine-tuned to work perfectly with the frame, offering optimal damping straight from the showroom floor. And adjusting your set-up? It's still quick and easy with simple hand adjustments, giving you full control to dial it in.
• SWINGARM: Cast from one piece of aluminum, the swingarm on this GASGAS certainly looks the business! A strong chain slider ensures durability and keeps the chain running smooth for long time. At the rear of the swingarm you'll find a chain guide with a rounded profile to help it glide over the ground as you lay the bike over through deeply rutted turns. Finally, clear chain adjustment markings ensure quick and easy maintenance.

Motor

• ELECTRONIC FUEL INJECTION (EFI): Our 2-stroke motors are fueled using Throttle Body Injection - a 39mm Keihin throttle body, to be precise - which works together with the Engine Contol Unit (ECU) to deliver the perfect mix of fuel and air. The end result? Crisp, clean running motors that create smooth, strong power. A protection cap for the CPC fuel connector adds extra safety and keeps dirt out, while the in-line fuel filter remains easily accessible for maintenance.
• CYLINDER & PISTON: With the introduction of electronic fuel injection on the MC 250, the traditional 2-stroke power valve is replaced with an innovative electronic exhaust control system. Now, the lateral exhaust ports opens slightly faster than the main exhaust port to deliver strong power and maximum reliability.
• TRANSMISSION: As the 5-speed gearbox is made by PANKL Racing Systems, you just know that the transmission is as good as it gets in terms of positive gear changes, reliability, and overall quality. The clever lever design helps prevent dirt build-up, too, especially when the ruts get deep and the dirt gets sticky!
• CRANKSHAFT: The magic at the heart of the motor and its low weight means one thing - it revs fast! It's also perfectly balanced for minimal vibration and positioned to have the least amount of effect on overall handling.
• CRANKCASE: Making sure the weight of the MC 250 is kept to a minimum, the thin and strong crankcases are made using a high-pressure die cast process. Inside, the motor internals are positioned to centralize mass, which leads to next level rideability.
• EXHAUST SYSTEM: Designed and developed to be slim using an innovative manufacturing process, looks awesome, and most importantly, delivers the very best performance! The header pipe is shaped for maximum ground clearance and is fitted to a muffler that features a clever internal construction to keep noise to a minimum without sacrificing power.
• DIAPHRAGM STEEL (DS) CLUTCH: Inside the MC 250 motor you'll find a robust and super reliable Damped Diaphragm Steel (DDS) clutch housed inside a CNC machined steel basket. This style of clutch does away with traditional coil springs and instead, there's a single diaphragm steel pressure plate and a damping system which helps get the power to the ground.

Parts

• HYDRAULIC BRAKES: Fast is fun but slowing down is essential, which is why all GASGAS dirt bikes are fitted with high quality BRAKTEC calipers and controls. Speaking of controls, the rear brake pedal is extra strong to prevent it from getting bent out of shape in a crash or catching the ground when you're railing through a deep rut. When you combine those BRAKTEC calipers with GASGAS specific brake discs, 260mm up front and 220mm at the rear, the end result is amazing braking performance. This all means that all riders can stay on the gas longer and brake later into corners. And we all know what that leads to... faster lap times!
• HYDRAULIC CLUTCH: No need for adjustment and offering a near maintenance-free operation, the best thing about the BRAKTEC hydraulic clutch is that it provides consistent action. With free-play at the redesigned lever automatically adjusted, the biting point and function of the clutch remain constant no matter whether the motor is started from cold or used during the heat of a battle.
• RADIATORS: Keeping the motor cool are a set of strong aluminum radiators, which channel the air through them in the most effective way possible. A large center tube within the frame is used to reduce the number of hoses needed and ensures a consistent flow of coolant around the engine - just what you need when you're in the heat of a battle! Plus, a cooling radiator closure makes operation easier, allowing for quicker and smoother maintenance when needed.
• WHEELS: Now in sleek black and built to take a beating, our wheels are ready to play rough. No matter how heavy the landing or how rough the track is, the silver, CNC machined hubs, lightweight spokes, and high-strength EXCEL rims deliver maximum strength for complete peace of mind.
• TIRES: One of the only components carried over from the outgoing generation of GASGAS motocross bikes are the Maxxis MaxxCross MX-ST tires. Need to know why? It's simple. They perform so well on a wide variety of terrain and they're super-durable too. After all, who likes changing tires?

Style

• GRAPHICS: Black graphic details bring a bold twist to the signature GASGAS red, with a clean white logo that pops right off the dark background. Other blacked-out parts like the seat cover, handlebar, and rims dial up the style to really set things off. Thanks to durable IML technology, the graphics are built into the bodywork to keep your GASGAS looking sharp, ride after ride.
• BODYWORK: Proudly red, with sharp black details! Incredibly ergonomic with large contact surfaces to help you grip the bike with your legs, the smooth profile bodywork encourages riders to effortlessly move around on the bike and ride with a perfect technique. There's also a super grippy seat cover, now in black, to keep you sat exactly where you need to be when you get on the gas!
• HANDLEBARS: Get on the gas and hold on tight! Not too tight though as nobody likes arm pump... But to make sure the ride is comfortable, black NEKEN handlebars are clamped into optimized bar mounts (they're more resistant to twisting if you should hit the deck), with lock-on style, medium compound ODI grips fitted to create a comfy set-up to suit all riders.
• AIRBOX: Less time working on bikes means more time riding bikes, which is precisely why you'll love the straightforward, no tools and no-nonsense filter mounting system. With a stronger one-piece design for the air intake, maximum airflow is guaranteed, and you know what that means... maximum power! Like before, accessing the air filter to inspect or replace it couldn't be easier. Simply pop the left side panel off and you'll be inside the airbox in no time.
• FUEL TANK: The fuel tank sits neatly inside the vibrant red bodywork and a beefie rubber tank support underneath helps hold it firmly in place while protecting the frame from wear. With an integrated fuel pump inside the tank, long motos around deep sand tracks aren't a problem for this GASGAS!
• FOOTPEGS: Bigger is better when it comes to footpegs. That's precisely why they not only have a large surface area for maximum grip, but we've also made them less likely to catch on the edges of deep ruts, which mean no loss to forward momentum. The pegs are also light and prevent mud from building up. So, no matter how gnarly the track gets, you'll stay in complete control.
